Description

Technical Field

[0001] The present invention relates to the technical field of nut conveying, and in particular to a nut conveyor. Background Art

[0002] A nut is a fastener used to connect and fix mechanical parts. It is usually used in conjunction with bolts, screws, etc. The internal shape of the nut is usually cylindrical, with a threaded structure inside that can mesh with the external thread of the bolt. The patent with patent announcement number CN212173635U relates to a nut feeding mechanism, including a base plate, a nut discharge mechanism and a nut pulling mechanism. The base plate is a flat plate with a smooth surface, and a nut feeding hole is provided on the base plate. The nut discharge mechanism is fixedly arranged at one end of the base plate. The nut discharge mechanism includes a base and a plurality of limit columns. A nut discharge hole is provided on the base. The limit columns are fixedly arranged around the nut discharge hole. The nut discharge mechanism includes a nut front and back pulling cylinder, a connecting plate and a nut clamping cylinder. The nut front and back pulling cylinder is fixed to the other end of the base plate and is arranged opposite to the nut discharge mechanism. The nut front and back pulling cylinder includes a piston rod that can be stretched along the direction of the base. The piston rod is sequentially connected to the connecting plate and the nut clamping cylinder from left to right. The patented mechanism is scientifically and reasonably designed, convenient and quick to use, and can greatly improve work efficiency.

[0003] The above patent has the characteristics of being easy and quick to use. By using a nut feeding mechanism, the operator only needs to place the nuts vertically in the arrangement position in advance. During production, the nuts will be automatically fed one by one, thereby effectively improving work efficiency. However, the limit rod is fixed on the base, which limits the size of the nuts that can be used. When the nut size exceeds the limit of the limit rod, the operator must stop the machine and remove the limit rod for adjustment, which not only increases the downtime, but also affects the continuity of the production process.

The circumferential surface of the limit rod contacts the inner wall of the No. 1 limit groove, and the surface of the limit rod in contact with the No. 1 limit groove is separated during movement, so that the limit imposed by the limit rod on the L-shaped plate is released.

[0008] According to the above technical scheme, it also includes a protective device and an auxiliary device; the protective device includes a fixed plate, a rotating rod, a roller, a cylindrical rod, a return spring, a contact plate and a linkage rod.

The spherical surface 1 of the cylindrical rod contacts the inclined surface 1 of the contact plate during movement, so that the moving cylindrical rod is affected by the inclined surface 1 and moves toward the drum.

[0010] According to the above technical scheme, the auxiliary device includes a hollow frame, a sleeve plate, a short rod, a C-shaped frame, a rotating shaft, a rotating plate and a blocking block. The movement of the sleeve plate drives the short rod to move in a direction away from the cylindrical rod, and the circumferential surface of the short rod contacts a side of the rotating plate close to the blocking block during the movement.

[0011] According to the above technical solution, a No. 2 spiral spring is arranged between the rotating shaft and the C-shaped frame. The No. 2 spiral spring is deformed when stretched, and the deformed No. 2 spiral spring stores energy under the action of its own elasticity. The rotating plate itself is elastic, and an arc surface 1 is provided on the side of the rotating plate away from the blocking block.

[0012] According to the above technical solution, a second arc surface is provided on one side of the blocking block close to the rotating plate, and the second arc surface contacts the surface of the rotating plate. The rotation of the rotating shaft drives the rotating plate to rotate rapidly toward the blocking block, and the rotating plate collides with the second arc surface during rotation to generate vibration.

[0013] The working principle and beneficial effects of the present invention are: 1. In the present invention, the friction between the movement of the nut and the corrugations is generated, so that the speed of the nut movement is effectively controlled by the influence of the friction force, and the corrugations are opened on the rubber plate, which effectively controls the speed at which the nuts fall downward, and ensures that the nuts can be smoothly arranged in the discharge frame, thereby improving the stability of the arrangement and reducing the confusion that occurs during the nut falling process. At the same time, the grip rod is pulled to move, so that the contact surface between the limit rod and the No. 1 limit groove is separated. Through simple operation, the operator can adjust the rectangular plate under standard operation more quickly and efficiently, which is convenient for the operator to flexibly adjust according to the size of different nuts, effectively reducing the downtime, thereby improving production efficiency.

[0014] 2. In the present invention, the circumferential surface of the roller takes over the contact between the push plate and the bottom of the arranged nuts, and the roller provides support for the nuts during rotation, so that the roller takes over the top of the push plate to contact the arranged nuts, effectively reducing the wear on the bottom of the nuts when the push plate moves, avoiding the surface of the nuts from being scratched, thereby ensuring the integrity of the nuts during transportation. At the same time, the contact plate provides support for the moving cylindrical rod, so that the supporting force provided by the contact plate can be stably transmitted to the moving push plate, thereby improving the stability of the movement of the push plate, thereby ensuring that the nuts can stably move to the inclined plate for transportation.

[0015] 3. In the present invention, multiple rotating plates collide with the arc surface 2 during rotation to generate vibration, and then the vibration is transmitted to the roller in contact with the arranged nuts, so that the arranged nuts are affected by the vibration, which helps to reduce the jamming of the nuts when they move. At the same time, when the linkage rod is reset, the circumferential surface of the short rod squeezes the rotating plate during movement, and the rotating plate is deformed by the squeezing. By providing the arc surface 1 on the rotating plate, the additional resistance applied to the short rod when the rotating plate is deformed is effectively reduced, so that the normal resetting of the linkage rod will not be affected when the rotating plate is squeezed, thereby improving the smoothness of the work.

The pushing plate 13 is driven to move back and forth by the electric push rod 12 to realize the intermittent delivery of the arranged nuts to the conveyor belt 4, which helps to avoid the nuts from piling up and increasing the difficulty of subsequent processing.

[0021] A No. 1 spiral spring is arranged between the rubber plate 17 and the rectangular plate 16. Corrugations are provided on the side of the rubber plate 17 away from the L-shaped plate 14. By providing the corrugations on the rubber plate 17, the speed at which the nuts fall downward is effectively controlled, ensuring that the nuts can be smoothly arranged in the discharge frame 11, thereby improving the stability of the arrangement and reducing the confusion that occurs during the falling of the nuts.

[0022] The Z-shaped piece 19 itself is elastic, a No. 1 limit groove is opened on the top of the rectangular box 10, a No. 2 limit groove is opened on the top of the rectangular box 10, and the circumferential surface of the limit rod 21 contacts the inner wall of the No. 1 limit groove. Through simple operation, the operator can adjust the rectangular plate 16 under standard operation more quickly and efficiently, which is convenient for the operator to flexibly adjust according to the size of different nuts, effectively reducing the downtime, thereby improving production efficiency.

[0023] In this embodiment, the nuts are placed one by one in the discharge frame 11, and the nuts move downward and contact the corrugations of the rubber plate 17. The nuts squeeze the rubber plate 17 during movement, and the rubber plate 17 rotates in the direction of the L-shaped plate 14 due to the squeezing. The rubber plate 17 stretches the No. 1 volute spring during rotation, and the No. 1 volute spring is deformed due to the stretching. The deformed No. 1 volute spring applies a reaction force to the rubber plate 17, and the rubber plate 17 applies additional resistance to the moving nut under the action of the reaction force. The downward movement speed of the nut is slowed down by the influence of the additional resistance. At the same time, the corrugations are affected by the reaction force and are in close contact with the surface of the nut, so that the nut continues to move and generates friction with the corrugations. The movement speed of the nut is further effectively controlled by the influence of the friction force, and the nut at the bottom moves slowly. During the movement, it contacts the top of the carrying plate 7, and the nut at the bottom is blocked and stops moving. At the same time, the carrying plate 7 provides support for the nuts arranged inside the discharge frame 11. After the nuts are arranged, the drive motor 5 is started, and the output end of the drive motor 5 drives the transmission roller 3 to rotate. The rotation of the transmission roller 3 drives the conveyor belt 4 to rotate, and the electric push rod 12 is started. The output end of the electric push rod 12 drives the push plate 13 to move in the direction of the inclined plate 8. The push plate 13 moves and contacts the nut, so that the push plate 13 moves and drives the nut to move in the direction of the inclined plate 8. The nut contacts the inclined surface of the inclined plate 8 during the movement, so that the inclined plate 8 guides the nut to move downward, and the nut contacts the conveyor belt 4 during the movement, so that the conveyor belt 4 rotates and drives the nut to move in the direction away from the inclined plate 8, and at the same time, the top of the push plate 13 The rubber plate 17 is provided with corrugations to effectively control the speed at which the nuts fall downward, thereby ensuring that the nuts can be smoothly arranged in the material discharging frame 11, thereby improving the stability of the arrangement and reducing the confusion that occurs during the nut falling process. When the position of the rectangular plate 16 needs to be adjusted, the gripping rod 20 is held and moved upward, and the gripping rod 20 drives the lifting plate 18 to move upward. The lifting plate 18 squeezes the Z-shaped piece 19 during movement, and the Z-shaped piece 19 is squeezed and deformed. At the same time, the lifting plate 18 moves and drives the limiting rod 21 to move upward. The surface of the limiting rod 21 in contact with the No. 1 limiting groove is separated during movement, so that the limiting rod 21 is pressed against the L-shaped plate 16. The limit imposed by 14 is released, and the gripping rod 20 is pulled to move away from the discharge frame 11. The gripping rod 20 moves to drive the lifting plate 18 to move away from the discharge frame 11. The lifting plate 18 moves to drive the limit rod 21 to move away from the discharge frame 11. At the same time, the lifting plate 18 moves to drive the L-shaped plate 14 to move away from the discharge frame 11. The L-shaped plate 14 moves to drive the connecting rod 15 to move toward the gripping rod 20. The connecting rod 15 moves to drive the rectangular plate 16 to move toward the gripping rod 20. The rectangular plate 16 moves to drive the rubber plate 17 to move toward the gripping rod 20. When the L-shaped plate 14 moves to the predetermined position, the gripping rod 20 is released, and the deformed Z-shaped piece 19 recovers under the action of its own elasticity. The recovery of the Z-shaped piece 19 drives the lifting plate 18 to move downward.The movement of the lifting plate 18 drives the limit rod 21 to move downward, and the circumferential surface of the limit rod 21 contacts the inner wall of the second limit groove during the movement, so that the limit rod 21 applies a limit to the L-shaped plate 14. Through simple operations, the operator can adjust the rectangular plate 16 more quickly and efficiently under standard operations, which is convenient for the operator to flexibly adjust according to the size of different nuts, effectively reducing the downtime, thereby improving production efficiency.

[0024] Example 2 like Figures 1 to 8 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes a protective device and an auxiliary device; the protective device includes a fixed plate 221, a rotating rod 222, a roller 223, a cylindrical rod 224, a return spring 225, a contact plate 226 and a linkage rod 227, the fixed plate 221 is fixedly penetrated through the top of the push plate 13, the rotating rod 222 is rotatably mounted on the inner wall of the fixed plate 221, the roller 223 is fixedly mounted on the circumferential surface of the rotating rod 222, and the cylindrical rod 224 is slidably penetrated through the fixed plate 22 1, the return spring 225 is arranged between the cylindrical rod 224 and the fixed plate 221, the contact plate 226 is fixedly installed on the inner wall of the rectangular groove, the linkage rod 227 is fixedly installed on the inner wall of the cylindrical rod 224, the linkage rod 227 slides through the inner and outer walls of the fixed plate 221, and the top of the push plate 13 is replaced by the roller 223 to contact the arranged nuts, which effectively reduces the wear of the bottom of the nut when the push plate 13 moves, avoids the surface of the nut from being worn, and thus ensures the integrity of the nut during transportation.

[0025] A spherical surface is provided on one side of the cylindrical rod 224 away from the fixed plate 221, and an inclined surface is provided on one side of the contact plate 226 close to the cylindrical rod 224. By setting the cylindrical rod 224, the supporting force provided by the contact plate 226 can be stably transmitted to the moving push plate 13, thereby improving the stability of the movement of the push plate 13, thereby ensuring that the nut can be stably moved to the inclined plate 8 for transportation.

[0026] The auxiliary device includes a hollow frame 231, a sleeve plate 232, a short rod 233, a C-shaped frame 234, a rotating shaft 235, a rotating piece 236 and a blocking block 237. The hollow frame 231 is fixedly installed on the bottom of the inner wall of the fixed plate 221, the sleeve plate 232 slides through the inner and outer walls of the hollow frame 231, the short rod 233 is fixedly penetrated on the surface of the sleeve plate 232, the C-shaped frame 234 is fixedly installed on the inner wall of the hollow frame 231, the rotating shaft 235 is rotatably installed on the inner wall of the C-shaped frame 234, the rotating piece 236 is fixedly installed on the circumferential surface of the rotating shaft 235, the blocking block 237 is fixedly installed on the bottom of the C-shaped frame 234, the sleeve plate 232 is fixedly connected to the circumferential surface of the linkage rod 227, and is fixedly connected to the linkage rod 227 through the sleeve plate 232, ensuring that the roller 223 vibrates when it contacts the nut, effectively improving the accuracy of vibration use.

[0027] A No. 2 scroll spring is arranged between the rotating shaft 235 and the C-shaped frame 234. The rotating piece 236 itself is elastic. An arc surface 1 is provided on the side of the rotating piece 236 away from the blocking block 237. By providing the arc surface 1 on the rotating piece 236, the additional resistance applied to the short rod 233 when the rotating piece 236 is deformed is effectively reduced, so that when the rotating piece 236 is squeezed, it will not affect the normal resetting of the linkage rod 227, thereby improving the smoothness of the operation.

[0028] A second arc surface is provided on one side of the blocking block 237 close to the rotating plate 236, and the second arc surface is in contact with the surface of the rotating plate 236. Continuous vibration is generated through the collision between the rotating plate 236 and the blocking block 237, and the vibration is then transmitted to the roller 223 in contact with the arranged nuts, so that the arranged nuts are affected by the vibration, which helps to reduce the jamming of the nuts when moving.

[0029] In this embodiment, the push plate 13 moves while driving the fixed plate 221 to move toward the inclined plate 8. The fixed plate 221 moves and drives the rotating rod 222 to move toward the inclined plate 8. The rotating rod 222 moves and drives the roller 223 to move toward the inclined plate 8. When the push plate 13 pushes the nut to move, the top of the push plate 13 contacts the bottom of the nuts arranged in the discharge frame 11. The push plate 13 continues to move and separates from the arranged nuts, so that the circumferential surface of the roller 223 replaces the push plate 13 and contacts the bottom of the arranged nuts. The roller 223 moves and contacts the bottom of the nuts. Friction is generated, and the roller 223 rotates under the influence of friction. At the same time, the roller 223 provides support for the arranged nuts during rotation. The roller 223 takes over the contact between the top of the push plate 13 and the arranged nuts, which effectively reduces the wear on the bottom of the nuts when the push plate 13 moves, avoids the surface of the nuts from being scratched, and thus ensures the integrity of the nuts during transportation. When the fixed plate 221 moves, it drives the cylindrical rod 224 to move toward the contact plate 226. The spherical surface of the cylindrical rod 224 contacts the inclined surface of the contact plate 226 during movement. The inclined plane 1 impedes the moving spherical surface 1, so that the moving cylindrical rod 224 is affected by the inclined plane 1 and moves toward the roller 223. The movement of the cylindrical rod 224 drives the linkage rod 227 to move toward the roller 223. At the same time, the cylindrical rod 224 squeezes the return spring 225 during the movement. The return spring 225 is squeezed and deformed. The deformed return spring 225 exerts a reaction force on the cylindrical rod 224. The cylindrical rod 224 affected by the reaction force is in close contact with the contact plate 226, so that the contact plate 226 is the moving cylindrical rod 22 4 provides support, the cylindrical rod 224 continues to move and separates from the inclined surface, and at the same time, the cylindrical rod 224 and the contact plate 226 are in contact with each other, so that the support provided by the contact plate 226 is more stable, and the cylindrical rod 224 then transmits the supporting force to the push plate 13, and the push plate 13 steadily pushes the nut to move under the action of the supporting force. By setting the cylindrical rod 224, the supporting force provided by the contact plate 226 can be stably transmitted to the moving push plate 13, thereby improving the stability of the movement of the push plate 13, thereby ensuring that the nut can stably move to the inclined plate 8 for transportation; When the linkage rod 227 moves in the direction away from the cylindrical rod 224, the linkage rod 227 moves to drive the sleeve plate 232 to move in the direction away from the cylindrical rod 224, and the sleeve plate 232 moves to drive the short rod 233 to move in the direction away from the cylindrical rod 224. The circumferential surface of the short rod 233 contacts a surface of the rotating piece 236 close to the blocking block 237 during the movement. The movement of the short rod 233 applies a thrust to the rotating piece 236. The rotating piece 236 is affected by the thrust and rotates in the direction away from the blocking block 237. The rotating piece 236 rotates and the surface in contact with the arc surface is separated. At the same time, the rotating piece 236 rotates The rotation of the rotating shaft 235 drives the rotating shaft 235 to rotate. The rotating shaft 235 stretches the second scroll spring during the rotation. The second scroll spring is deformed by the stretching. The deformed second scroll spring stores energy under the action of its own elasticity. When the contact surface between the short rod 233 and the rotating piece 236 is separated, the deformed second scroll spring drives the rotating shaft 235 to rotate rapidly to the initial position. The rotation of the rotating shaft 235 drives the rotating piece 236 to rotate rapidly toward the blocking block 237. The rotating piece 236 collides with the second arc surface during the rotation to generate vibration, and the short rod 233 continues to move and contacts the second rotating piece 236, and then repeats the above. The above movement causes the short rod 233 to contact with the plurality of rotating plates 236 during movement, and the rotating plates 236 collide with the blocking blocks 237 to generate continuous vibration, which is then transmitted to the roller 223 in contact with the arranged nuts, so that the arranged nuts are affected by the vibration, which helps to reduce the jamming of the nuts when they move. When the linkage rod 227 is reset, the linkage rod 227 moves to drive the sleeve plate 232 to move in the direction close to the cylindrical rod 224, and the sleeve plate 232 moves to drive the short rod 233 to move in the direction close to the cylindrical rod 224. The circumferential surface of the short rod 233 contacts the rotating plates during movement. When the arc surface 1 contacts the rotating piece 236, the rotating piece 236 in the initial position cannot rotate toward the blocking block 237, so the short rod 233 continues to move and squeeze the rotating piece 236. The rotating piece 236 is squeezed and deformed. When the short rod 233 and the arc surface 1 are separated, the deformed rotating piece 236 recovers under the action of its own elasticity. By providing the arc surface 1 on the rotating piece 236, the additional resistance applied to the short rod 233 by the rotating piece 236 when it is deformed is effectively reduced, so that the rotating piece 236 will not affect the normal resetting of the linkage rod 227 when it is squeezed, thereby improving the smoothness of the operation.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
